Keystone denying claim (of course)

Keystone was pretty decent on things I complained about. I have the same cracks on my 2010 that I bought new. They said it was stress cracks and nothing to worry about. The worst part of it is I had to look at it on my brand new camper but in the long run they were right. It has had no adverse effect on the performance of the trailer and it never got any worse. I recommend not to drive yourself crazy over such a minor problem. Aggravating yes, but not really that big of a deal; imo.
Happy travels!
